75      <p>If you discover that UNIX print jobs result in a <span
76      class="emphasis"><i class="EMPHASIS">staircase</i></span>
77      appearance, then you need to force your printer to do
78      <acronym class="ACRONYM">LF</acronym> (linefeed) to <tt
79      class="FILENAME">CR/LF</tt> (carriage return/line feed)
80      translation, or do the translation yourself.</p>

99
100      <p>If you have a more complex printer that handles
101      PostScript, PCL, and PJL, then you will need to use the more
102      powerful <b class="APPLICATION">ifhp</b> filter:</p>
